Her manner was natural, free from conceit and from exhibitionism of her abilities. She had good habits of work and enjoyed the challenge of the mental tests. Her vocabulary, language responses, and abstract thinking were clearly on an adult level. She is credited by the examiner with remarkable degrees of mental control, concentration, constructive visual imagery, and manipulation of mathematical and verbal concepts, rote memory, and inductive reasoning. On a standardized test of reading ability she exhibited a Reading Age of 14 years 5 months at this time (7 years 10 months). Her writing was reported as excellent. Her earlier educational progress reflects her extraordinary ability. In her first six months at school she completed four terms of work. She was one term in Grade 3A, and then in one term passed through 3B, 4A, and 4B. J's parents had from the beginning given intelligent attention to her adjustments in school and to her friendships. She had been wisely guided, motivated to make friends rather than to be in constant leadership, and she was well liked and accepted by her classmates. At this early age the psychological examiner was able confidently to predict: "In view of her exceptional intelligence, her apparently good health, her apparently excellent social adjustment, she can be expected to attain distinction and to win leadership in higher educational and professional fields." LATER MENTAL TESTS J was given a second Stanford-Binet test by Dr. M. C. Pritchard within three days of her tenth birthday, on May 15, 1939, using the 1937 Revision, Form L. A Mental Age of 20 years was achieved which, if her limit had been reached, would have meant an IQ of 200--very like the 197 plus attaned at the earlier Chronological Age. On February 17, 1938, at the age of 9 years 9 months, J had also taken IER Intelligence Scale CAVD, Levels I to M, making a score of 384 points. Several records are available on the New Stanford Achievement Tests given, a different form each time, to the pupils in the experimental class at Speyer School at intervals of six months. Annual tests at the close of each school year, for a period of three years, may be used here to show J's ability and progress in these respects. Such scores are as follows: EDUCATIONAL AGE FUNCTION FORM W FORM Y FORM X FORM W June 16, June 1, May 31, May 18, 1937 1938 1939 1940
